Michelson interferometer with porch swing bearing for portable FTIR spectrometer

The interferometer for low resolution portable Fourier Transform middle infrared spectrometer was developed and studied experimentally. The final aim was a concept for a commercial prototype. Because of the portability, the interferometer should be compact sized and insensitive to the external temperature variations and mechanical vibrations. To minimise the size and manufacturing costs, Michelson interferometer based on plane mirrors and porch swing bearing was selected and no dynamic alignment system was applied. The driving motor was a linear voice coil actuator to avoid mechanical contact of the moving parts. The driving capability for low mirror driving velocities required by the photoacoustic detectors was studied. In total, four versions of such an interferometer were built and experimentally studied. The thermal stability during the external temperature variations and the alignment stability over the mirror travel were measured using the modulation depth of the wide diameter laser beam. Method for estimating the mirror tilt angle from the modulation depth was developed to take account the effect from the non-uniform intensity distribution of the laser beam. The spectrometer stability was finally studied also using the infrared radiation. The latest interferometer was assembled for the middle infrared spectrometer with spectral range from 750 cm−1 to 4500 cm−1. The interferometer size was (197 × 95 × 79) mm3 with the beam diameter of 25 mm. The alignment stability as the change of the tilt angle over the mirror travel of 3 mm was 5 μrad, which decreases the modulation depth only about 0.7 percent in infrared at 3000 cm−1. During the temperature raise, the modulation depth at 3000 cm−1 changed about 1 . . . 2 percentage units per Celsius over short term and even less than 0.2 percentage units per Celsius over the total temperature raise of 30 °C. The unapodised spectral resolution was 4 cm−1 limited by the aperture size. The best achieved signal to noise ratio was about 38 000:1 with commercially available DLaTGS detector. Although the vibration sensitivity requires still improving, the interferometer performed, as a whole, very well and could be further developed to conform all the requirements of the portable and stable spectrometer.

Transition : en betydelsefull fas i den långtidssjuka ungas vård

The aim of this caring science thesis is to deepen the understanding for the long-term ill adolescents care. In particular it aims to reach a better understanding of transition in health care, with a focus on how young people perceive health care. The goal is to build a model, a consistent theoretical framework that makes it possible to listen to the adolescent´s own voice, providing a better understanding of what good care consists in from their point of view. This Master's thesis consists of a literature overview on the concept of transition and a themed interview with young patients regarding transition of health care. The overall issue is 1. What is good care during the transition according to the adolescents themselves? 2. How does transition affect the young people's health and lives? The theoretical perspective of this thesis lies in the caring science tradition that has been developed at the Åbo Akademi University department of caring science with the caritative nursing theory as a basis. The epistemological and ontological assumptions are based on the caritative nursing theory, which in itself is ethical. Understanding of the concept of transition is based on A. Meleis transitions theory. The methodological approach is hermeneutical. The theme interview has been analyzed by using S. Kvales method. The material consists of a thematic interview with 10 long-term ill adolescents, about their views of the care received. This thesis research even in how NOBABs standards appears in the litterature as well as how they are implemented from the point of view of young people. The findings of this thesis shows that good care for the adolescent is a true presence with the young and an understanding of the direction in which the young move toward during the transition of care. Good care for an adolescent consists in being recognized as a person who is seen, known, appreciated and understood. Good care for the young involves recognizing her strength and joy of life including the contrast she experiences between health and suffering. To recognize their personal strength and courage supports the adolescents during the process of transitions of care Good care for the young involves responsibility for the individual person and humility in approaching her, giving attention to her view of life and aspirations. Openness and humility in the approach lays the foundation for a trusting relation during the transition of care. A unified theoretical framework is needed to promote the long-term ill adolescents care during transition of care. When the young and her individual needs is the centerpiece of healthcare creates this the basis for empowering care that supports the young in her quest for health. This master thesis adds a given model to the long-term ill adolescents` healthcare.

Kallet til livets embete : mødre i helse og lidelse

Mothers represent the natural caring. Natural caring is the object of caring science and of research interest because it establishes the central core of professional caring. In this study, we encounter patients who are mothers in need of care in a psychiatric context. Motherhood involves taking responsibility that extends beyond one's own life, because the child represents possibilities in a yet unknown future. Understanding and knowledge about the mothers' struggle in health and suffering are of crucial importance to enable clinical practice to make provisions for and adapt to the individual patient. The overall purpose of this dissertation is to illuminate how the innermost essence of caring emerges in health and suffering in patients who are mothers in psychiatric care. The purpose of the study in a clinical sense is to seek to understand and illuminate the patient's inner world in health and suffering in terms of contextual, existential, ontological and ethical dimensions. The dissertation is exploratory and descriptive in nature and encompasses induction, deduction and abduction as logics tools of reasoning. A theoretical model of natural caring and a universal theoretical model of the innermost essence of caring is developed as seen from the patient's world in a psychiatric context. The dissertation is anchored in human science's view of the human being and the world and in caring science's perspective. Caring science's view of the human being as a unity comprising body, soul and spirit is central in the study's concept of the patient. This multi-dimensional conception of the human being encompasses the dissertation's basic values and is decisive for choice of methodology. Hermeneutic epistemology guided the interpretation of the empirical data, the paradigmatic theses and assumptions. The dialectical movement in interpretation moves back and forth between empirical data, caring science theory and philosophical theory and reveals deeper insight into meaningful content in the clinical context. The interpretation process comprises four levels of abstraction: rational, contextual, existential and ontological. Hermeneutic philosophy guides the inductive and deductive approach to interpretation, as well as the movement between the clinical context and the caring science paradigm. In this encounter between the visible and invisible reality, the image of natural caring – motherliness emerged. The dissertation consists of four studies. The first study is a systematic review of nineteen research articles. The three other studies are hermeneutical interpretations based on text materials from open interviews. Fifteen participants were interviewed, all of whom are mothers of children between 0 and 18 years of age. All were outpatients in the psychiatric specialist health service. In the interpretation process, the mothers' struggle in health and suffering emerges as a struggle between the inner and outer world. Being a mother and patient in health and suffering in a psychiatric context means to struggle to be oneself, to create oneself, to live and realize one's good deeds as a mother and human being. To be oneself, to possess oneself as a mother is not only a question of tending, playing and learning in order to master a practical situation or to survive. It involves constituting a deep, inner desire to courageously create oneself so that the child is able to realize his or her potential in health and suffering. Motherliness manifests itself in caring as a call to ministering humanity and life. The voice of motherliness is understood as the voice of life—the eternal, inner call of love and freedom. The inner call craves fulfilment. Motherliness in natural caring does not retreat. Motherliness defines the Other as freedom and proceeds without regard for all other exterior requirements to realizing wellbeing. The inner essence of caring is attentive, aware and heeds the call of the heart. The innermost essence of caring is to be and to make oneself responsible for the Other. Responsibility cannot be relinquished; free choice consists in whether or not to follow the call. To renounce the inner call to responsibility is to deny oneself and one's dignity as a human being. The theoretical models provide clinical and systematic caring science with knowledge and understanding based on the natural caring spirit inherent in the human being. The study elucidates and strengthens the ontological basic assumptions about the human being as a unity of body, soul and spirit, the sanctity of the human being and the core of caring, ethos. The results of the dissertation will provide clinical practice with knowledge about the inner movements of the mothers' souls in relation to their responsibility as mothers and human beings. Being able to understand the basic conditions for responsibility is crucial for developing care that encompasses mother and child and the mutual relationship between them. This is basic knowledge for developing attitudes and actions that meet and provide for the needs of the patient as mother and as a whole, suffering human being.

6-n-propyltiouracil (PROP) taster status in Brazilian adults

The objective of this study was to determine PROP (6-n-propyltiouracil) taster status in adults and its relationship with anthropometric variables and pleasantness of sugar, salt, and fat. A total of 123 subjects rated the intensity of PROP and sodium cloride (NaCl) solutions using the labeled magnitude scale. For pleasantness evaluation, it was used concentrated orange juice (sugar) and mashed potato (salt and fat). The subjects were classified as non-tasters (n = 35), medium-tasters (n = 33) and super-tasters (n = 55). In this study, no relationship was found between PROP taster status and age, sex, weight, body mass index, and pleasantness. Although genetic markers may influence the degree of liking of certain foods, one must consider that the mechanisms influencing eating behavior in humans are complex, and that psychological, social, and economic factors play a key role in response to food.

Suitability of LiDAR technology for forest inventory in Russia

LiDAR is an advanced remote sensing technology with many applications, including forest inventory. The most common type is ALS (airborne laser scanning). The method is successfully utilized in many developed markets, where it is replacing traditional forest inventory methods. However, it is innovative for Russian market, where traditional field inventory dominates. ArboLiDAR is a forest inventory solution that engages LiDAR, color infrared imagery, GPS ground control plots and field sample plots, developed by Arbonaut Ltd. This study is an industrial market research for LiDAR technology in Russia focused on customer needs. Russian forestry market is very attractive, because of large growing stock volumes. It underwent drastic changes in 2006, but it is still in transitional stage. There are several types of forest inventory, both with public and private funding. Private forestry enterprises basically need forest inventory in two cases – while making coupe demarcation before timber harvesting and as a part of forest management planning, that is supposed to be done every ten years on the whole leased territory. The study covered 14 companies in total that include private forestry companies with timber harvesting activities, private forest inventory providers, state subordinate companies and forestry software developer. The research strategy is multiple case studies with semi-structured interviews as the main data collection technique. The study focuses on North-West Russia, as it is the most developed Russian region in forestry. The research applies the Voice of the Customer (VOC) concept to elicit customer needs of Russian forestry actors and discovers how these needs are met. It studies forest inventory methods currently applied in Russia and proposes the model of method comparison, based on Multi-criteria decision making (MCDM) approach, mainly on Analytical Hierarchy Process (AHP). Required product attributes are classified in accordance with Kano model. The answer about suitability of LiDAR technology is ambiguous, since many details should be taken into account.

Life-related negative customer emotions in real estate agent encounters

The goal of this study was to explore how do customers’ life-related negative emotions affect real estate business. This was divided into two research questions: 1. What life-related negative emotions can be recognised in real estate customer encounters? 2. How do the recognised emotions affect customer encounters and the realtor’s work? 3. How can the realtor take the emotions into account in customer service? The theoretical background consists of two main lines of study: emotions and customer encounters. A wide literary review on emotions research was conducted from a cognitive psychology point of view, focusing on negative emotions. Emotions research was then combined into the field of customer encounters. Qualitative study was chosen as the methodological basis of the study. Empirical material of this study was collected through in-depth interviews with 13 successful Finnish real estate agents. Narrative research was used as a method for the study. Four life-related emotion categories were recognized in real estate customer encounters: sadness, anger, anxiety and shame. These emotions rose from issues varying from death of a close one to divorce and from major changes in life stages to deep emotional attachment to an old home. The study also found that these incidental negative emotions do affect customer encounters and realtors’ work. The emotions affected the decision making of customers and sometimes overshadowed reason. Some emotions made the customer passive and slow to make any decisions, while others made their decision making fast and hasty. Even though the incidental emotions might not have had anything to do with the real estate deal, they could affect the outcome of the customer encounter and the whole real estate deal. Interestingly enough, the study found that not all successful real estate agents knowingly serve customers in an emotional level. The study does, however, suggest that in fact it may be an ethical decision of the customer server to take into account the emotional state of the customer. Attending to the emotional side of customers does not only increase pleasantness of the customer encounter, but may improve and balance customer decision making and prevent hasty decisions possibly leading to improved customer satisfaction. This study also gave practical managerial implications to customer service providers on how negative incidental emotions can be attended to in a customer encounter. This study could be useful not only to real estate agents, but also in other types of customer service, especially with vulnerable populations or other types of home-related business.

Vidrörd av livet i dödens närhet - att varda som människa och vårdare i vårdandets gemenskap

The overall aim of the study is to create a theory model of “becoming” as a human being and health care provider in the caring communion at the end-of-life. The theoretical perspective of the study is caring science as it is developed at Åbo Academy University in Finland outlined in Eriksson's theory of caritative caring with focus on caring ethics. The thesis consists of four sub-studies reported as scientific articles and a summary section. The study has an overarching hermeneutic research approach. The sub-studies I-IV are reinterpreted from viewpoint of the overall question. Empirical assumptions could then be discerned from the substance of the four substudies, which raised questions. The answers to these questions were sought in dialogue with selected texts by Kierkegaard and resulted in a theory model. The theory model results in following theses: 1. To “become” as a human being is to remain in an endless guilt. Guilt is a form of love. It is guilt that give strength and willingness to act in love and mercy when caring for patients at the end-of-life. The guilt as love allows becoming as a human being to be at home in love and mercy. 2. The human being’s courage is characterized as the willingness to obtain contact with the life of fellow human beings. This courage develops over time to stand for itself, with a foundation of belief in human beings, and resulting in a selfless, loving way to help the patients grieve and reconcile at the end-of-life. 3. To be “touched” can be illustrated as an inner awakening; an inner movement towards consciousness for the examination of the love for one another, and to love unselfishly. 4. The human being’s evolution in its own understanding of life occurs in the care of another human being who is at the end-of-life, as well as to be at home in ethos, love and mercy. Becoming in this context means that the human being evolves to become responsive to the heart's inner voice; an inner strength and joy which opens to the eternal and holy. 5. To overcome external obstacles is characterized as serving human beings in a selfless love; a caring in love that has requirements that need to be expressed by what is true, beautiful and good for patients at the end-of-life. An awareness and understanding of what it means to become as a human being and health care provider in caring community can help health care providers to easily focus on the patient.

The influence of physical attractiveness and gender on perceived competence of sportscasters

The media tends to represent female athletes as women first and athletes second (Koivula, 1 999). The present study investigated whether this same trend was present for female sportscasters, using a self-presentational framework. Self-presentation is the process by which people try to control how others see them (Leary, 1995). One factor that may influence the type of image they try to project is their roles held in society, including gender roles. The gender roles for a man include dominance, assertiveness, and masculinity, while the gender roles for a woman include nurturer, femininity, and attractiveness (Deaux & Major, 1 987). By contrast, sports broadcasters are expected to be knowledgeable, assertive, and competent. Research suggests that female sports broadcasters are seen as less competent and less persuasive than male sports broadcasters (Mitrook & Dorr, 2001; Ordman & Zillmann, 1994, Toro, 2005). One reason for this difference may be that the gender roles for a man are much more similar to those of a sportscaster, compared to those of a woman. Thus, there may be a conflict between the two roles for women. The present study investigated whether the gender and perceived attractiveness of sportscasters influenced the audience's perceptions of the level of competence that a sportscaster demonstrates. Two hundred and four male (n =75) and female (n =129) undergraduate students were recruited from a southern Ontario university to participate in the study. The average age of the male participants was 21 .23 years {SD =1 .60), and the average age for female participants was 20.67 years {SD = 1 .31). The age range for all participants was from 19 to 30 years {M = 20.87 years, SD = 1 .45). Af^er providing informed consent, participants randomly received one of four possible questionnaire packages. The participants answered the demographic questionnaire, and then proceeded to view the picture and read the script of a sports newscast. Next, based on the picture and script, the participants answered the competence questionnaire, assessing the general, sport specific, and overall competence of the sportscaster. Once participants had finished, they returned the package to the researcher and were thanked for their time. Data was analyzed using an ANOVA to determine if general sport competence differs with respect to gender and attractiveness of the sportscaster. Overall, the ANOVA was non-significant (p > .05), indicating no differences on the dependent variable based on gender (F (3, 194) = .631, p = .426), attractiveness (F (3, 194) = .070, p = .791), or the interaction of the two {F (3, 194) = .043,/? = .836). Although none of the study hypotheses were supported, the study provided some insight to the perceived competence of female sportscasters. It is possible that female sportscasters are now seen as competent in the area of sports. Sample characteristics could also have influenced these results; the participants in the current study were primarily physical education and kinesiology students, who had experience participating in physical activity with both men and women. Future research should investigate this issue further by using a video sportscast. It is possible that delivery characteristics such as voice quality or eye contact may also impact perceptions of sportscasters.

Registered nurses' perceptions of factors impacting on their continuing education /

This qualitative study examined the effects of hospital restructuring on a group of nurses at a community hospital. Eleven nurses were asked questions in order to gain insight into their experience in this situation. Ten of these participants were female, and one was male. The intent was to gather information about how restructuring has affected their lives, including, their motivational factors and barriers to participation in continuing education, and their descriptions of their workplace environment. Audiotaped interviews were conducted on two occasions to obtain this data. Emergent themes included the nurses' comments about continuing education, motivational factors, barriers that included geography and time, reactions of co-workers, restructuring, the College of Nurses' Quality Assurance Program including peer feedback, and performance appraisals. The literature review compares the barriers and motivational factors to the previous research findings. Thus, this study gave voice to the experience of this group of nurses, working in a healthcare setting that is involved in restructuring. This information is important to the healthcare system, since many areas are involved in restructuring. The whole process, if it is to be successful, depends on the frontline workers, namely the nurses. Thus, if there is anything to be learned from this group of people, that could be used to improve this progression, everyone would benefit from this information, were it to be implemented. Everyone is a stakeholder in the quality of healthcare in our province. The frontline workers are the ones that hold the vantage point to be able to provide suggestions for the changes needed to successful. These nurses are not just motivated by work issues however, and educating them and motivating them will also improve the care provided through increased knowledge and enhanced self-esteem.

Academics as parents--parents as academics : a study of the integration of intellectual and child-care labours /

Discussions concerning the challenges of combining work and family are certainly not new, and still actively continue. There is, however, a silence in the related literature regarding a comprehensive description of integrating specifically university academic ~. work and family responsibilities. This silence is especially evident for men who are parents as well as academics. With the participation of 4 key informants, this qualitative research study gave voice to men and women who participate in the academic labour of a Canadian university as professors, and as graduate students, along with the parenting labour of at least 1 child under the age of7. Methodology was developed to reveal in-depth perspectives regarding the work practices employed by 4 key informants as they combined intellectual and child-care responsibilities. Multiple data collection methods included journal reflections, day time observation sessions, a focus group, and a final evaluation questionnaire. Using research findings, together with information extrapolated from Three Models of the Family (Eichler, 1997), this study also took steps toward developing a Proposed "Three Models of the University," to offer explanation for the work practices of the key informants as academics/parents, and also for future consideration in university policy formation.

Adolescent females' self-concept and physical education : a Q-sort analysis /

This research illuminates the relationship between female adolescents' self-concept and their experience of physical education. This was accomplished through three stages of interviews and a Qsort. The topics through which the research was categorized included peer support, teachers as significant others, meaningful connections to the body, and curriculum content. During stage one female physical education specialists, curriculum coordinators, and adolescents were interviewed to develop Q-items for the Q-sort. The second stage Involved two groups of females between the ages of 12 and 14 years who participated in the Q-sort. The final stage involved an insight group that consisted of four Q-sort participants who interpreted the highest ranking Q-items. Critical to this research was giving these adolescents the opportunity to voice what was important to them. The results of the research included descriptions of the elements in physical education that were deemed most important by female adolescent students. The topics of "peer support" and "meaningful connections to the body" were ranked the highest. By interpreting the rich insights of the discussion group, it was found that peers were most influential to these young girls. Perceiving and bestowing respect were imperative in this stage of their lives.
